Method: Shotgun metagenomic sequencing (CLIA 21D2062464); not cleared or approved by the FDA. Results reflect relative microbial abundance for wellness education purposes. Not intended to diagnose or treat disease and not a substitute for clinical consultation. Microbial associations are based on emerging scientific research and may change over time.
A derived biomarker is a value that is calculated from other directly measured biomarkers rather than being measured directly in the lab.
Key benefits of Saccharomyces testing
- Saccharomyces yeast monitoring
- fermented food intake and probiotic tracking
What is Saccharomyces?
Saccharomyces is a yeast genus best known for S. cerevisiae (baker's/brewer's yeast) and S. boulardii, a probiotic. Detection in the gut microbiome often reflects dietary sources - fermented foods, nutritional yeast, beer, wine, and S. boulardii supplements. Detected by shotgun metagenomic sequencing.
Why is Saccharomyces important?
Saccharomyces boulardii is one of the most studied probiotic yeasts and may support gut microbiome recovery after antibiotic treatment. Its detection may reflect active supplementation. Overall Saccharomyces levels are context-dependent.
What insights will I get?
Your Saccharomyces level may reflect fermented food consumption, nutritional yeast use, or S. boulardii probiotic supplementation. Tracking levels may reveal how dietary yeast exposure affects your gut fungal ecosystem over time.
